Zajac et al. (2014) found that dolomite powder of cement paste at a curing temperature of 60 °C was partially dissolved after 180 d; correspondingly, the inner calcium silicate hydrate (C-S-H) had a denser microstructure. At a curing temperature of 20 °C, the dolomite powder in cement paste was rarely involved in hydration reaction after 180 ...
The present study focuses on utilizing stockpiled dolomite quarry waste for sustainable and cleaner production of concrete. Natural river sand is substituted with dolomite quarry waste at 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and in concrete mixes. The test findings revealed the concrete mix made with 10% dolomite quarry waste displayed …
